This highlight reports on the still poorly understood transition to an electron crystalline state (the Wigner crystal) in a two-dimensional system at extremely low densities, observable at low temperatures as a function of magnetic field. This experiment finds a surprising stabilization of the Wigner crystal arising from magnetic-field-induced spin alignment. Such electrically-delicate samples require the ultra-low-noise environment and experimental techniques available at the High B/T facility.
Study of helium atoms at low temperatures illuminate extreme quantum effects that were earlier predicted.
Scientists found that the emergence of an exotic quantum mechanical phase in Ce1-xNdxCoIn5 is due to a shape change in the Fermi surface. This finding ran counter to theoretical arguments and has led investigators in new directions.
This research established experimental evidence for the long sought-after transition of a small, two-dimensional sheet of electrons to a solid state.
New materials that exhibit a strong coupling between magnetic and electric effects are of great interest for the development of high-sensitivity detectors and other devices. This paper reports on such a coupling in a specially designed material.
Experiment shows that emergent quantum fluid behavior of helium-3 confined to one dimension is observable using special low-temperature NMR techniques.
Observing growth processes in classical alloys is extremely difficult; scientists overcame this by studying quantum systems.
At high magnetic field, free-flowing particles condense into “puddles.”
Controlled by electron interactions, the Mott transition is accompanied by a reduction in the volume of the atomic lattice.
Working with a solid form of helium at ultra-low temperatures, scientists observed a quantum phase separation that may shed light on analogous processes in classical systems like metal alloys.
